The invention relates to a climbing arrangement comprising a climbing surface and a rotatable endless belt suspended on a frame structure and having on its surface several grip holds for forming a climbing surface. The frame structure comprises side sections on opposite edges of the belt with a first side section beside a first edge of the belt and a second side section beside the opposite edge of the belt, and a support frame for supporting the frame structure.
Climbing arrangements of this type are known from WO publication 98/32496, for instance. They are suitable for use in sports parks and sports centers, for instance.
A problem with the known climbing arrangements is that they require a lot of space, which is why their installation in most different sites of use may be problematic. Their large size also makes them heavy and difficult to transport, which means that they are difficult to move.
An object of the invention is to provide a climbing arrangement that eliminates said drawbacks of the known devices and requires only a little space and is physically placeable in most different sites of use.
The climbing arrangement of the invention comprises a rotatable endless belt suspended on a frame structure and having a surface comprising several grip holds for forming a climbing surface, and the frame structure comprises side sections on opposite edges of the belt with a first side section beside a first edge of the belt and a second side section beside the opposite edge of the belt, a support frame for supporting the frame structure, which support frame is arranged to support the frame structure asymmetrically from only one side of the frame structure by means of a vertical support that is removably fastened to the support frame, in such a manner that the vertical support settles beside only one of the two side sections; and in the climbing arrangement, the frame structure is arranged to fasten to the vertical support optionally on the side of the first side section or second side section; and the support frame comprises first fastening means and second fastening means for fastening the vertical support to the support frame optionally at a first point so that the vertical support settles beside the first side section when the climbing arrangement is assembled, or at a second point so that the vertical support settles beside the second side section when the climbing arrangement is assembled.
The support frame of the climbing arrangement preferably comprises a rectangular planar support for supporting the climbing arrangement on a base, whereby the first and second fastening means for fastening the vertical support are also preferably arranged on the edge area of the planar support. At said point, the vertical support can be mounted so that it does not interfere with the use of the climbing support. If the planar support comprises a first edge and an edge opposite the first edge, and the first fastening means are arranged on the first edge and the second fastening means are arranged on the second edge, the same planar support can be utilized to provide a “left-handed” or a “right-handed” climbing support. Thus, there is no need to manufacture and store different components depending on the handedness of the climbing arrangement. Therefore, the side sections of the climbing arrangement are preferably also connected to the vertical support with a common axle that is arranged to extend through holes in the side sections.
The edge of the planar support and a straight line drawn from the first fastening means to a point where the side section fastens to the vertical support preferably form an acute angle of 50 to 80 degrees, whereby the first and second fastening means are preferably also arranged close to the corners of the planar support. Owing to this arrangement, the support frame of the climbing arrangement interferes as little as possible with the use of the climbing arrangement, and a padded mat can also be placed centrally with respect to the frame structure of the climbing arrangement, which in turn reduces the space requirement of the climbing arrangement.
The frame structure supporting the belt is preferably triangular, which means that the tightness of the belt can be easily adjusted, the belt can be made long with respect to the size of the climbing arrangement, and inside the belt, there is a lot of space for various actuators, such as belt rotating devices and frame structure turning devices, which in turn makes it possible to make the climbing arrangement small and compact.
Preferred embodiments of the invention are disclosed in the attached dependent claims 2 to 17.
The greatest advantages of the climbing arrangement of the invention are that its space requirement is small and it is easy to install in different environments. Thus, it is suitable for use for example in sports centers, gyms, sports parks, amusement parks, arcades, venues, ski centers, spas, and even hotels. Due to its small size, it can also be made relatively light and easy to transport. The size of the climbing arrangement is typically 2.2.5 m (width譴ength議eight), for instance. Due to the asymmetric support of the frame structure, the width of the climbing arrangement is small. If the endless belt of the climbing arrangement is arranged to rotate on three turning points, the belt can be made long with respect to the height of the climbing arrangement, which in turn makes it possible to provide a large number of grip holds on the climbing surface and versatility to the climbing arrangement.
In the following, the invention will be described by means of one preferred embodiment and with reference to the attached drawing, in which
The climbing arrangement of the invention is shown as a general view in
The belt 1 can be rotated so that a person using the climbing arrangement feels to be climbing even though s/he is essentially stationary with respect to the frame structure 4. The belt 1 can be rotated in both directions, which means that it is possible to climb “downwards”, if desired.
The frame structure 4 can be inclined to set the climbing surface 3 at different angles. The double arrow drawn in
The frame structure 4 comprises two side sections 6, 7 that settle on corresponding edges 8, 9 of the belt 1. More specifically, the circumferential area of the side sections 6, 7 has edges, inside which the edges 8, 9 of the belt can extend so that there is no gap between the belt edges and side sections. The solution is safe for the user of the climbing arrangement and also prevents rain water from entering inside the frame structure that contains various structures (to be described later in the text) for rotating the belt, inclining the frame structure, etc. Reference number 43 indicates elongated, preferably housing-like members for rigidly connecting the side sections to each other.
The support frame 5 comprises a vertical support 10 that at point K is arranged to support the frame structure 4 at a distance S=approximately 1.5 m from the base, see
The support frame 5 is arranged to support the frame structure 4 asymmetrically from one side by means of the support 10. Thus, the support 10 is only beside one side section 7 of the climbing arrangement. Owing to this arrangement, the width of the climbing arrangement can be made small, because a safety distance between the vertical support and frame structure need not be arranged on both sides of the support structure 4—because there is only one vertical support. Because the support 10 points upwards, it is referred to as a vertical support 10 in the following. The safety distance G between the vertical support 10 and frame structure 4 is at least 18 cm, for instance 20 cm. The safety distance G is necessary to prevent the fingers of a user of the climbing arrangement from getting jammed between the vertical support 10 and frame structure 4 when the climbing arrangement is being inclined.
The vertical support 10 is fastened with screws 50 or other fastening means to the desired fastening plate. The opposite sides of the vertical support 10 are similar in shape and structure. Thus, at point K of the vertical support 10, where a dead axle 17 according to
A line drawn from the fastening plate 13 to point K of the vertical support 10 forms an acute angle α=70 degrees with respect to the edge support 11 of the planar support 15, and the fastening plate 13 is also arranged close to the angle of the planar support. Therefore, the frame structure 4 is supported in such a manner that the vertical support 10 does not interfere with the use of the climbing arrangement, and the planar support 15, to which a padded mat 16 is to be arranged (see
The padded mat 16 (not shown in
The frame structure 4 of the climbing arrangement is, as seen from the sides, triangular in shape. The belt 1 is arranged to run over three turning lines T1, T2, and T3, see
Because the frame structure 3 is triangular, the radius of the rolls 22 to 27, 51, 52 in the turning lines can be small, for instance 15 cm, and there still remains a large space inside the triangular frame for the various components. Reference numbers 28 and 29 indicate centralization rolls that are arranged to run at the same speed as the belt. When the belt 1 moves, its edges 8 and 9 settle between the centralization rolls 28, 29 and the belt 1 does not come on top of them. Due to the centralization rolls 28, 29, the belt 1 does not move much sideways, which prevents the edges 8, 9 of the belt from chafing against fixed structures, which might cause the belt to wear quickly.
Turning angle β1 of the belt 1 at turning line T1 is approximately 15 degrees (see
An electric motor 33 or some other actuator for running the belt 1 is arranged inside the triangular space defined by the belt 1. The electric motor 33 is arranged to run a belt 53 with belt pulleys 30, 31. Instead of the belt 53 and belt pulleys 30, 31, it is possible to use a chain and gears. Belt pulley 30 is arranged on a rotating axle 32. The earlier mentioned rolls 22 to 24 are arranged on the rotating axle 32. On turning line T2, there are three (or two) rolls. Of these rolls, rolls 25 and 26 are shown in the drawing. One of the rolls can be an adjusting wheel 25 that adjusts the tightness of the belt 1. The position of the adjusting wheel 25 can be mechanically moved to tighten (or loosen) the belt 1.
Reference number 34 indicates an actuator for inclining the frame structure 4. The actuator comprises an electric motor arranged inside a housing-like member 43, the motor being arranged to move by means of a gearbox and preferably a stiff longitudinally adjustable elongated member, such as a telescopic rod, a power transmission means on the axle 17 in such a manner that the frame structure 4 inclines relative to the axle 17.
The frame structure 4 is mounted by bearings 36, 37 on the axle 17. At the bearing points, there are flanged fastening sleeves 38, 39 that settle between the axle 17 and the walls of the holes 40 in the side sections 6, 7 (see
Reference number 42 indicates a vibration motor that can be used to produce vibration to the belt 1, if desired.
Above, the invention is described by way of example only and it should be noted that the details of the invention may be implemented in many ways within the scope of the attached claims. Therefore, the structure and location of the actuators belonging to the climbing arrangement may vary as may the design of the support frame and the design of the frame structure.
